RMS File Extension

Have a problem opening a .RMS file? We collect information about file formats and can explain what RMS files are. Additionally we recommend software suitable for opening or converting such files.

What is the .RMS file type?

The primary association of the .rms extension belongs to the Record Management System (RMS) file format/type. RMS is a database-like binary format used by Java ME (Java, Micro Edition by Oracle) applications to persistently store their settings and configuration data. Java ME is a popular proprietary platform for mobile devices, such as cellular phones, early smartphones, etc.

An .rms file is a binary byte-array file that can be accessed by a Java ME application to read/write data for storage between sessions. There is no standard format for RMS files, and each application may handle its .rms storages differently. RMS storages are often used as save-game files by many mobile games.

Some Java-based software for older mobile devices stores confidential information (passwords, etc.) in RMS files either in plaintext or with a simple XOR encryption, presenting a security/privacy risk.

Additionally, the .rms extension has an association with the RealMedia Secure Media File (RMS) file format and type. Developed by Real Networks, Inc., RMS is a proprietary container format for stream-serving DRM-protected digital multimedia content. The use of Real Networks software (RealPlayer, etc.), including web-browser plugins, is required to play RMS files.

Lastly, the .rms extension is also assigned to Random Map Script (RMS) files used in several RTS (Real-Time Strategy) games by Microsoft, including the Age of Empires and the Rise of Nations series. An .rms file is a script that generates a custom random scenario map, normally located in the "Random" subfolder of the game installation directory (e.g., "C:\Program Files\Microsoft Games\Age of Empires II\Random").
